Proposal summary

To successfully thrive in the genitourinary tract C. glabrata has to cope with numerous stresses including the presence of organic acids at a low pH that are produced by the co-colonizing microbiota and also azoles which are used as antifungal agents. This thesis will be focused on elucidating, at a genome-wide scale, how C. glabrata cells respond to these two stresses, either alone or in combination. Emphasis will be put on the role played by the CgPdr1 and CgHaa1 regulons, considering their demonstrated essential role in response to those stresses. It will also be examined whether these two regulatory systems may contribute for pathogenic traits of C. glabrata including virulence in different infection models or ability to form biofilms in biotic or abiotic surfaces.
